ADJUSTABLE RADIATOIlt-E'AN'.

Speccation of Letters Patent.

Patented July 8, 1919.

To all whom t may concern:

Be it known that I, WILLIAM G. WEATH- ERLY, a citizen of the United States, residing at Los Angeles, in the county of Los Angeles and AState of California, have invented new and useful Improvements in Adjustable Radiator-Fans, of which the followin/Iis a specification.

object is to make an adjustable radiator an so that the fan may be adjusted to neutral position in cold weather and may be adjusted to draw more or less air as desired in warm weather or when the radiator becomes Warm, and 'my invention consists in' the novel features herein shown, described and claimed.

Figure 1 is a diagrammatic view showing an adjustable fan applied to the radiator of a motor vehicle in accordance with the principles of my invention'.

Fig. 2 is a fragmentary elevation of the adjustable fan.

Fig. 3 is an enlarged central sectional detail with the parts adjusted to hold the fan neutral.

Fig. 4 is a view analogous to Fig. 3 with the parts adjusted to hold the fan blades to catch the wind.

Fig. 5 is a cross-sectional detail on the line 5 5 of Fig. 2.

Fig. 6 is a fragmentary sectional detail on the line 6 6 of Fig.. 4.

The post 1 extends upwardly from the base of the engine 2 and has a bearing 3 in its upper end. The spindle 4 is clamped in the bearing 3 by a. set-screw 5, said spindle having a central bore 6 extending from end to end. `The fan hub 7 is rotatably mounted upon thespindle 4, The fan pulley 8 is integral with the hub 7 and bears against the bearing 3. A retaining flange 9 is formed upon the forward end of the spindle 4. A liange 10 is formed upon the forward end of the hub 7. A cup-shaped housing 11 i'snplaced with its bottom a ainst the front .-face of the flange 10.- Radial arms l2 are placed vWith their inner ends against the rear face of the flange 10 and the parts 10, 11 and 12 aresecured together by rivets 13. Slots v14.h are formed radially through the rim of the housing 11. An annular chan neled rim 15 has bearings 16 evenly spaced apart and the rim is secured in place by placing the outer ends of the arms 12in the channel and inserting rivets 17 so as to hold the rim 15 concentric to the hub 7, and the outer ends of the arms 12 are slightly inclined or bent forwardly. The fan blades 18 have pintles 19 mounted in the ybearings 164 and have cranks 20 extending from their inner ends through the slots 14. A shifting head 21 has an annular groove 22 in its periphery and the inner ends of the cranks 2O are mounted in this groove. A shifting rod 22 extends from the head 21 through the bore f6. A bearing bracket 23 is secured to the post l, and a lever 24 is pivotally connected to the bracket 23 by a pin 25 and pivotally connected to the rear end of the rod 22 by a pin .26. A sector 27 is mounted upon the steering post casing 28 in position convenient to the operator, a hand-lever 29 is pivotally mounted upon the sector, and a rod 30 is connected to the hand-lever 29 and extends through the cover 31 and is connected to the other end of the lever 24 by a pin 32. A cap 33 fits upon the housing 11 and has half bearings 34 fitting against the cranks 20 to hold the cranks steady in the slots 14, and the cap is secured in place by cap screws 35. An expansive coil spring 36 is inserted between the cap 33 and the front face of the shifting head 21, the tension of the spring being exerted to hold the fan in neutral position.

Normally, the hand-lever 29 is pushed down, thereby operating the shifting rod 22 to pull the head 21 against the ange 9 and this movement operates the cranks 20 to turn the fan blades 18 to their neutral positions so that the rotation of thefan will not draw any air. When the weather is warm or when the'radiator warms up the hand-lever 29 is moved toward the operator to any desired extent, thereb Swingin the fan blades into operation to raw air t rough the radiator and cool the radiator.

The inner ends of the cranks-20 travel in the groove 22 of the head 21 and the position of the head 21 in the housing 11 determines the operation of the fan blades. i

Thus I have roduced a fanfor cooling a. radiator whic may be adjusted from neutral position to operative position and back from a hand-lever mounted upon the steering post.

Various changes may be made in the details of construction without departing from the spirit .of my invention as claimed.

I claim:

1. In a radiator' fan, a post adapted to be secured t0 the base of an engine and extend upwardly therefrom; a bearing at the upper end of the post; a spindle clamped in the bearing, said spindle having a central bore extending from end to end; a fan hub rotatably mounted upon the spindle; a fan pulley integral with the fan hub; a retaining fiange upon the forward end of the spindle; a second flange upon the forward end of the hub; a cup-shaped housing mounted with its bottomagainst the front face of the second flange; radial arms having their inner ends fitting against the rear face of the second flange; the housing, second flange and radial arms being secured together by rivets; there being radial slots through the rim of the housing; an annular channeled rim having bearings evenly spaced apart, the outer ends of the radial arms being fixed to the rim and the outer ends of the arms being slightly bent forwardly; fan blades having pintles mounted vin the bearings in the rim andhaving cranks extending from their inner ends through the slots in the housing; a shifting head within the housing and having an an-l nular groove into which bthe cranks extend; a shifting rod extending fr0m the head through the bore in the'spindle; and means for shifting the rod to feather the fan blades.

2. In a radiator fan, a post adapted to he secured to the base of an engine and extend upwardly therefrom; a bearing at the upper end of the post; a lspindle clamped in the bearing, said spindle having a central bore extending from end to end; a fan hub rotatably mounted upon the spindle; a fan pulley integral with the fan hub; a retaining flange upon the forward end of the spindle; a second flange upon the forward end of the hub; a. cupshaped housing mounted with its bottom against the front face of the second flange; radial-arms having'their inner ends fitting against the rear face of the second flange; the housing, second flange and radial arms being secured together by rivets; there being radial slots through the rimof the housing; an annular channeled rim having bearings evenly spaced apart, the outer ends of the radial arms being fixed to the rim and the outer ends of the arms* being slightly bent forwardly; fan blades having pintles mounted in the bearings in the rim and having cranks extending from their inner ends through the slots in the housing; a shifting head within the housing and having an annular groove into which th'e cranks extend; a shifting rod extending from .the head through the bore in the spindle; means for shifting the rod to feather the fan blades; a cap fitting upon the housing and having half bear-ings matching with the slots in the housing t0 hold the cranks steady; and an expansive coil lspring inserted between the cap and the frontface of the shifting head, the tension of the spring being exerted to hold the fan blades in neutral position.

In testimony whereof I have signed my name to this specification.

WILLIAM G. WEATHERLY.
